These guys are freaking awesome I had a idea on these fjordur mini bosses and I think when you kill them you should get a egg that when you hatch it it gives you a tamed but weaker version of these guys, beyla, and steinbjorn!
Hati and sköll are twin bosses much like the fenrir. They summon fenrirs. Hati is yellow and sköll is blue. They ARE NOT DIREWOLVES the pictures that pull up on the internet are false they are fenrirs.
